Steps to Take

 

 

 

STATUS LED is not lit

1.

Check LEDs on other modules and cards. If none are lit, refer to Table 2-3to

 

 

check the status of the power modules (AC PEM or DC PEM).

 

2.

If LEDs on other modules and cards are lit, remove the card from its slot and

 

 

check for bent or broken pins on the backplane. Return the card to its slot and

 

 

screw it firmly into place.

 

3.

Replace the card.
